WebIt’s a universal standard for low-voltage test devices that describes four overvoltage installation categories. The higher the number of the category is, the bigger the danger presented by the transients is. The categories don’t depend as much on the voltage level, but more on the fault current that’s available in the distribution system. WebDefinition: Voltage surge is defined as the sudden rise in excessive voltage which damages the electrical equipment of an installation. The overvoltage in the lines occurs because of …
